1996 993 Check Engine Light + Exhaust Rattle

Vehicle Information: Model: 993; Year: 1996; Body Type: Coupe; Total Mileage: 67000;

Recently the check engine light came on and remains on. This occurred the same time what appears to be exhaust rattle just presented itself. What could be the problem? Loose/damaged catalytic converter, loose/damaged muffler, something else? Thanks!Region: PeachstateTotal Mileage: 67000Car Use: Street use only
